Statistical motivation

• Error reporting for remotely gathered bedding orientations is difficult
• Many Mars mapping studies report no error ranges, or poorly repeatable errors based on unstated assumptions
• Lack of visualization tools makes it difficult to assess relative quality of measurements

1. The rotated coordinate basis that underlies PCA.
2. A generalization of possible nominal planes to a hyperbolic error space in two dimensions.
